It is one group.
After reconstitution steps, marking unit 230 can constitute the data group for marking recombination.For example, respective negative carries
The name Auto-matching set is as unregistered with the relevant each load device classification of pre-stored load device data group
Temporal sign data.As an example, A, B, C etc. can be automatic by data pattern and matching storage data technique
Be registered as refrigerator, television set, washing machine etc..
In addition, in one embodiment, label can receive manually.Although executable automatic label, developer or user
Also can name manually due to pre-stored load device erroneous matching and unregistered load device and input title.Make
Method with the switch time of device is also effective.
In addition, corresponding data and the log-on data of each load device store respectively together, implement in load device
Hand labeled is to extend pre-stored load device data group.
In addition, electric energy measurement information flag server 200 can be by using the electric energy use information of each load device
To provide data analysis information.The data analysis of Behavior-based control psychological analysis technology can operate with the total work of each load device
Rate and electric energy use pattern generate specific data group with production.
In addition, the expert consulting prompt for promoting user to save electric energy can be automatically generated by data analysis.
Moreover, integrated service is also effective, can be lived to specific building and unit by the IT professional suppliers of electric energy
Total electric energy, service condition, the electric energy that residence provides each load device save consulting etc..
The example that various electric energy save consulting can be, such as when monitoring and each relevant differentiation of load device state
When the aggregated data group of component-level changes, in order to determine the assembly life-span state or failure shape of each load device
State, it is necessary to provide a user determining assembly life-span state or malfunction.
According to embodiment, the hardware of gauge table and the software technology of server are combined, so as to from power inputs
The electric energy use information of the various components of different loads device is extracted in total electric energy use information.
In addition, because the software technology of server can be not necessarily to multiple because installing with single device for measurement of electrical energy flexible combination
High cost caused by the system of device can extract the detailed and accurate electric energy use information of each load device, with
Realize that high-end electric energy saves scheme.
In conclusion in the present invention, each load device is extracted in total power consumption measured by power inputs
Electric energy use information when, particular server does not implement all technologies.Different from traditional mechanism, advance data processing is executed,
So as to the resolution with the various components for distinguishing over single device for measurement of electrical energy, and server centered is executed as its advantage
Data storage, pattern analysis and data utilize, so that it is determined that related to processing big data, storage big data or management different loads
The flexibility that uses of electric energy.
It can in the order shown, in a different order or synchronous implement different operation shown in Fig. 4, operation, side
Frame, step etc..In addition, in some embodiments, in without departing from the scope of the present invention, it is convenient to omit, increase, change, skipping
